WE’RE all aware that weeds are a pesky addition to any garden, due to the fact they’re an eyesore and can do plenty of damage to your patio.

Japanese Knotweed, or Reynoutria Japonica, is a rapidly spreading weed that grows into bamboo-like stems, potentially reaching as high as 7ft. 

This perennial weed is a well-known nuisance, not only because they suppress all other plant growth, but also as they’re incredibly difficult to get rid of. 

Eradication requires the help of a professional, due to the fact it’s hard to remove by hand or with chemicals, thanks to its creeping roots. 

And leaving even the tiniest amount in your soil means there’s a chance it’ll grow back next Spring. 

So, it’s important to spot it early – and here’s what to look for. 

In spring, reddish-purple fleshy shoots emerge from crimson-pink buds at ground level. Then, once established, it can be recognised by its bamboo-like stems and small, white flowers.

You might also notice purple flecks along the canes and heart or shovel-shaped leaves. 

Just be sure not to confuse it with Russian vines, Himalayan Honeysuckle or Red Dragon. 

It’s often found in waysides, flower beds, along borders, and in between paving slabs. 

But not only is it a nightmare to tame, but it can also get you in legal trouble – as homeowners can be fined anything up to £34,000 if Japanese Knotweed is spotted in their garden. 

However, a recent lawsuit saw a seller forced to pay £200,000 after his property was found to be overrun with green stems. 

Explaining why the plant is such an issue financially, pros at the Japanese Knotweed Expert said: “Japanese knotweed can decrease the value of a property by up to 20%. It can also be difficult to raise a mortgage on a property blighted with Japanese knotweed. 

“Additionally, you may be liable to cover the cost of the remediation of the Japanese knotweed once you have purchased the property.”
